The center pills, which are probably blue or green, are just placebo pills. You can skip the last week of pills and start a new pack immediately. It is safe, I have done it a couple of times. Just skip the placebo or sugar pills as they are sometimes called, and start a new pack.
And if I start a new pack skipping the placebos I won't get my period right. Will the next period after that be more heavy.
No, if you skip then it will not make the next one heavier! Good luck and have fun!
